LG PlayZ issues

Hi,
I've install PlayZ and there is two issues:
1. Media Played via PlayZ doesn't get marked as complete (Samsung Plex Client markes items as complete so I know it the LG PlayZ app that not marking them complete)
2. Fast forward on PlayZ will just jump 30 secs ~ 1 min 30 into the media. Is there a stand fast forward button like the client on my Samsung Plex Client?

Thanks
